Thermodynamics cannot yield any information about the intermediate states of a given reacting system. These intermediate states are the subject matter of chemical kinetics, which studies reaction rates and mechanisms. Chemical kinetics will predict what chemicals are present while thermodynamics…
One of the largest costs of monitoring gas levels is the ongoing cost of sensor calibration. The TR250Z Oxygen Sensor and O2/CO2 Combination Sensor are both designed to be calibrated in situ with the push of a button using normal…
Ammonium ion loading is an important parameter for determining the amount of pollution in water. With this new ammonia electrode (photo), which has replaceable modules and membranes, it is possible to perform the appropriate analyses economically, says the company. Ammonium…
This company now offers an intrinsically safe Bluetooth module for wireless transmission of measured data from its laser shaft-alignment systems. Now it is possible to work wirelessly in explosive environments. Using the Bluetooth module eliminates the use of cable connections…
The iTCX transmitter is designed to allow users to monitor temperature from two independent thermocouple channels over an Ethernet network or the Internet with no special software aside from a Web browser. Serving active Web pages, the transmitter displays realtime…
An EtherCAT fieldbus interface is now available for this company’s thermal mass flowmeters and controllers for gases and liquids, as well as its digital pressure controllers. EtherCAT is said to be a highly flexible Ethernet-network protocol that operates at high…
ReactIR 247 (photo) is a process-hardened Fourier transform infrared (FTIR) spectrometer designed to fit into nearly any space without sacrificing performance. Designed for classified environments, the instrument is engineered to be simple to operate, highly compact, cost effective and have…
The new wSeries Wi-Fi transmitter communicates on a standard Wi-Fi network, which is an economical solution for facilities with an existing Wi-Fi network as well as for new installations. Transmitters are available for analog voltage (0–10 V) and current (4–20…
A digital pressure gage combines the accuracy of digital technology with the simplicity of an analog pressure-measuring device. Given its very high sampling rate of 100 measurements per second, the CPG500 digital pressure gage (photo) is able to capture fast…
Version 8 of the Simatic PCS 7 process-control system boasts a host of new functions. The new features range from improved data exchange and an easier engineering workflow, more powerful communication, redundancy-related and fault-tolerant functions to new controllers and extended…
